Button on mouse click inside of Server Connect Variable

How do you insert the html in your app, probably the html is not being parsed by app connect.

You can test following code, just place it in a javascript file or include it directly on your page:

dmx.Attribute('html2', 'mounted', function(node, attr) {
    this.$addBinding(attr.value, function(value) {
        this.children.splice(0).forEach(function(child) {
            child.$destroy();
        });
        
        this.bindings = [];
        node.innerHTML = value || '';
        
        this.$parse(node);
    });
});

The in your code inject the html like:

<div dmx-html2="serverconnect1.data.buttonCode"></div>
